Teaching Activities:
At the professional level, Dr. Marky lectures in Medicinal Chemistry I where he is the course coordinator, Medicinal Chemistry II, and one elective course "Therapeutic Applications of Proteins and Nucleic Acids".  At the graduate level, Dr. Marky is the course coordinator for Quantitative Pharmaceutical Analysis and Biophysical Chemistry. In addition, he lectures in Advanced Medicinal Chemistry, and Macromolecular Structure and Function. Dr. Marky is a former Fulbright Scholar (Peru-98).

Research Activities/Interests:
The research interests of Dr. Marky are in the area of biophysical chemistry and focus on the molecular forces that control the conformational stability and flexibility of nucleic acids, including Okazaki fragments, hairpin loops, intramolecular triplexes, G-quadruplexes, C-quadruplexes, and three- & four-arm DNA junctions and their interaction with drugs. One objective is to improve the delivery of oligonucleotides into cells and drugs, by using natural and synthetic polymers, to block gene expression. His research group is also investigating the role of water on the conformational stability of biomolecules by examining sequence hydration effects in nucleic acids, drug-nucleic acid complexes, DNA covalent adducts, and protein-DNA interactions.
